Amazon 1 year after launch: Unfortunately, the space needed for robots in the van means that the van has to return to base 5 times more often to reload with the actual packages and the extra weight of robots more than doubles the weight of the van being lugged around in the form of heavy robots. So that’s why we are having to charge more for delivery and why it is taking longer for you to get your packages. But at least we can pay fewer salaries.
